Was looking for budget wireless follow focus and found version of this controller that comes with the wireless servomotor to operate focus of manual lenses or on cameras that don't support electronic focus. I asked aliexpress seller if this version is able to work as wireless follow focus on other setups - other gimbals etc. He answered that he didn't test it that way but the only problem should be to power the servo. Decided not to buy it only due to short operating range.
